plasmashell not running at boot or login

Leap 42.2 and my applications (VirtualBox, keme) are running now but there were issues and conflicts along the way. I probably caused this one myself.
After booting I am obliged to open a terminal and run plasmashell manually. This process connects the wifi and provides an application launcher, date and time, etc.
What is the best way to make this automatic?

SOLVED this one myself:
Yast > Software manager > View > Patterns > select kde-plasma
It loaded about 25 files and then I rebooted for good measure.
